Dear aspirant,

You can like study totally free in nits /IITs but yes there are various scholarships or reimbursement provided by the colleges on the basis of family income. Because of this you have to pay a very little amount in course of 4 years.

For families whose income is below 5L per annum but greater than 1L they would get remission of 2/3 rd of their tuition fees.

For families whose family income is below 1 lakh per annum will get full remission of the tuition fees.

If these remissions are availed then cost comes down to 3-4 L in 4 years for 2/3 rd remission ones for for full remission ones it is around 2.5L to 3L.
